Azure Active Directory authorization

I'm trying to do user authorization though AAD in azure app with own client side. I have a user named "User" in my AAD with password "pass". When user is trying to connect the app: 

            try
            {
                if (false == Utils.DataBaseUtils.CheckLoginCorrect(sceneMessage.Login, sceneMessage.Pwd))
                {
                    WriteToLog("Wrong password");
                    SendError(handler, "Wrong password");
                    return;
                }
            }
            catch (Exception e)
            {
                WriteToLog("Unexpected problem when checking password: "+e.ToString());
                SendError(handler, "Unexpected problem when checking password");
                return;
            }

    //authorization using Azure Active Directory
    public static bool CheckLoginCorrect(string login, string password)
    {
        if (string.IsNullOrEmpty(login) || string.IsNullOrEmpty(password))  //validatecredentials return true if log or pass is empty
            return false;

        using (PrincipalContext adContext = new PrincipalContext(ContextType.Domain, "mydomain156.onmicrosoft.com"))  //represent AD
        {
            return adContext.ValidateCredentials(login, password, ContextOptions.Negotiate);
        }
    }

Where sceneMessage.Login == "User", sceneMessage.Pwd == "pass". Here I'm getting error:

System.DirectoryServices.AccountManagement.PrincipalServerDownException: The server could not be contacted. ---> System.DirectoryServices.Protocols.LdapException: The LDAP server is unavailable.

Could anybody help, please?

Azure Active Directory Authentication Library (ADAL, formerly AAL) is the correct API to use for authenticating users in Azure Active Directory. Version 1 has been released and you can find more information here:

It looks like you're using the AD libraries for traditional on-premise AD. To program against Azure AD, use the Auzre Authentication Library (AAL). Note, last week AAL was renamed to Active Directory Authentication Library.
